Title: X-ray fluorescent analysis
Inventor: NISHINO MAKOTO
IPC: G01N23/223
Filed: 1996-07-25
Abstract: PURPOSE: To enhance the accuracy of quantitative calculations of a sample containing elements which cannot be measured fluorescent X-rays by utilizing the Compton scattering ray intensity of a first-order X-ray in the quantitative calculations. CONSTITUTION: Carbon, oxygen, and hydrogen in an analytical sample are first measured for their intensities using an X-ray fluorescent analytical device (S1). Next, the initial values of contents WC, WO, WH, i.e., the composition light of the carbon, oxygen, and hydrogen in the sample, are set (S2). Then, from the initial values of contents WC, WO, WH and using FP method, theoretical values of the integral intensity IC of CKα , the peak intensity IO of OKα , and the scattering intensity ratio IRhKα C/R of RhK are calculated (S3). This calculated theoretical intensity is multiplied by an element sensitivity coefficient, and measured intensity estimated from the assumed contents is calculated (S4). The estimated measuring intensity is compared (S5) with actually measured intensity for the correction of the assumed contents, so that 100% standardization is performed (S6). Next it is determined (S7) whether or not the correction width of the corrected contents is, e.g. 0.1% or less, and when it is 0.1% or less, the final corrections are determined as the contents.

Abstract: PURPOSE:To decrease the fluctuation of a current due to process fluctuation by providing a 1st current mirror circuit and a 2nd current mirror circuit each comprising a transistor(TR) whose emitter is connected to a constant voltage source and a diode. CONSTITUTION:TRs Q3, Q7 and Q4 and Q8 form respectively current mirror circuits. Moreover, the collector current of a TR Q1 is equal to the collector current or the TR Q3 because the TR Q1 and a diode D1 form a current mirror circuit when the junction area of the TR Q1 and the diode D1 is equal to each other. Then the TRs Q7, Q3 are formed the same structure, and only the base- emitter junction area of the TR Q3 is made twice that of the TR Q7 or the TRs Q3, Q7 are formed to the same structure and same size, and 2 TRs Q3 are connected in parallel. Thus, even when the TR characteristic is changed due to process variance, the collector current of the TR Q3 is constant and the collector current of the TR Q1 is unchanged, then the fluctuation of the current due to process variance is reduced.

When the state 22 is transited and the signal 41 is detected within a specified time, the state is transited to the state 23 awaiting the reception of the signal 41 and an address signal 44 received only for a time assigned to its belonging group. The receiver transited to the state 23 receives the signal for a predetermined time assigned to its own group and compares it with its own address and when the both are equal, the code word is received successively. When the received signal is a message signal 45 and a stop control signal, the control section 4 sets each section of the receiver to the stop state and stops its own operation.

Filed: 1993-08-09
Abstract: PURPOSE:To prevent damages which can occur due to thermal stress at the time of starting a hot-banked boiler on connection part between a furnace wall and a heat recovery area, suppress the decrease of main steam pressure at starting and stabilize the flow rate of feed water introduced into the furnace wall. CONSTITUTION:Low temperature fluid C1 which has been held in lower part of a hot-banked furnace wall 1 is extracted downward before a feed water pump 8 is started. High temperature fluid H1 held in upper part of the furnace wall 1 is not immediately sent to a steam separator 12. The high temperature fluid H1 is sent to the steam separator 12 after high temperature fluid H2 which has been held in upper part of an economizer 6 is sent to the lower part of the furnace wall 1. In this way, low temperature fluid C2 flows to a furnace wall outlet A after the high temperature fluids H1, H1 has been sent. The high temperature fluid and the low temperature fluid, therefore, do not repeatedly alternate with each other in passing through the furnace wall outlet A. Fluctuating thermal stress is not applied on the connection part of the furnace wall 1. The boiler is prevented from being cooled by the discharge of the low temperature fluid, that is, the decrease of the main steam pressure is suppressed and the variation of water level HL in a steam separator tank 13 caused by pressure does not occur repeatedly so that the feed water flow rate is stabilized.
